A 55 lb child carrying an 11 lb backpack is the equivalent of a 155 lb adult going to work every day with 31 lbs on their back. That is why orthopedists repeat the 10% rule: a full backpack should not exceed one tenth of the weight of the person carrying it.
How to weigh it (takes 1 minute)
Bathroom scale: weigh the child without the backpack, then with Monday's packed backpack (the worst day). The difference is the number that matters. Above 10%, something must go; above 15%, it is urgent.
Layered packing
- Against the back: the heaviest items (big books). Weight far from the back becomes a lever against the spine.
- Middle layer: notebooks and pencil case.
- Front and pockets: the light stuff: snack, planner.
- Always both straps: a one-shoulder backpack doubles the load on one side. Adjust the straps so the bottom of the pack ends at the waistline.
What usually can go
- A 10-subject binder when the day has 4 classes: one thin notebook per day solves it.
- A bottle filled at home: if school has a fountain, leave half empty.
- The 24-pen arsenal case: six items do the same job.
- The big toy «to show»: agree on one fixed day of the week for that.
The warning signs
Red marks on the shoulders, a child leaning forward while walking, pain complaints at the end of the day. Any of the three: re-weigh the backpack. And remember the bright side of lightness: a child without extra weight comes home with energy to play, color and still enjoy a bedtime story. 🐾
